Genus Rliopcea /b?n?cZ hi the Fiji Islands. 321 



and elytra, and clothed with closely-^et minute yellowish 

 setse, except upon the breast, which is densely covered 

 with moderately long yellow hair. The head is rather 

 coarsely sculptured and scantily setose, and the pygi- 

 dium is rather closely rugose and setose at the sides, 

 with a quite bare, smooth, longitudinal area along the middle. 

 The legs are slender and the tarsi not long, those of the 

 hind legs very short in the female. The antennal club of 

 the male is not very long (rather shorter than the foot-stalk), 

 with the fourth joint minutely spinose, the fifth about half 

 the length of the club, the sixth a little shorter than the 

 latter and the last four of equal length.

Two specimens of each sex were sent, together with the 

 other and apparently commoner species. It is closely similar 

 to R. vestita, but rather more narrow and elongate, with the 

 sculpture of the pronotum and elytra considerably less fine 

 and dense, the clothing of grey setse less close, and the 

 surface exhibiting a silky lustre which is absent from the 

 other species. The pygidium is rather coarsely punctured 

 and scantily setose all over, without any trace of the smooth 

 median area characterising R. vestita. The clypeus is less 

 finely punctured and its front margin more strongly excised, 

 the sides of the pronotum are less sharj^ly angulated and 

 the hind angles blunter. The antennal club of the male is 

 a little longer, the fourth joint of the antennae is produced 

 into a short lamella, the fifth is only a little shorter than the 

 club, and the last five are of equal length. 



The remaining Fijian species, R. vitiensis, Fairm., is larger 

 than cither of the new species, with the seta3 upon the upper 

 surface more irregularly distributed and the elytra rather 

 coarsely rugose, without definite punctures.
